    Study Notes

    Types of Algae

    • Brown algae is known for its large, multicellular marine species commonly called seaweeds.
    • Red algae gets its distinctive color from the pigment phycoerythrin, which allows them to photosynthesize at greater depths.
    • Green algae is known for its spiral or helical chloroplasts, as seen in Spirogyra.

    Structures of Algae

    • Rhizoid is not a root-like structure, but rather a holdfast anchors some seaweeds to rocks.
    • Stipe is a structure found in some seaweeds, but it's not the root-like structure.
    • Blade is a structure found in some seaweeds, but it's not the root-like structure.
    • Algin is the gelatinous material found in the cell walls of brown algae.

    Movement and Nutrition

    • Dinoflagellates are a group of algae that can move using flagella.
    • Mixotrophy is the process by which some algae can switch between autotrophic and heterotrophic modes of nutrition.

    Other Facts

    • Chlamydomonas nivalis is a type of algae that can be found in snow, giving it a pink or red hue, and is known as “snow algae”.
    • Stigma is the eye-like structure that detects light in some motile algae.
    • Euglenoids are a group of algae characterized by the presence of two flagella, one of which is typically wrapped around the cell body.
